Description
Technical field
The utility model is about a kind of high-tension bus-bar checkout equipment, the insulator intelligent detection equipment that refers in particular to the scalable intelligent magnetic test pencil of a kind of high pressure and use this test pencil.
Background technology
Along with the further enforcement of national intelligent grid planning, UHV transmission line plays a part crucial to national intelligent grid construction, has also just become the normal indispensable part in service of UHV transmission line at the repair based on condition of component of UHV transmission line.Wherein, transmission line of electricity has the insulator that is used for fixing conductor, and insulator is the vitals that makes conductor maintenance electric property, thus most important to the regular detection of insulator, be the essential step of UHV transmission line repair based on condition of component.
At present, the intelligent checkout equipment of the insulator of domestic ultrahigh voltage alternating current transmission lines is less, existing checkout equipment as shown in Figure 1, (patent No. is: CN201120449131.X) to have a UHV transmission line insulator intelligent detecting instrument 9, leaning out two diameters from intelligent detecting instrument 9 is the parallel steel bar test pencil 91 of 2-3mm, during measurement, operating personnel's both hands grip and intelligent movable detector 9, the test side that makes two steel bar test pencils 91 is the two ends of the steel cap 81 of connect insulator 8 respectively, in order to detect the insulator physical characteristics.
Yet in the actual measurement operation process, adopt above-mentioned Equipment Inspection insulator still to have following problem:
1. the two ends of the steel cap of insulator are cylindrical structure (as Fig. 1), when its test side with the steel bar test pencil contacts, only be line contact even some contact, cause contact area less, loose contact easily is again because intelligent detecting instrument is that the operating personnel hands, when hand has shake, just more increased the incidence of loose contact situation, finally made measurement result inaccurate;
2. in measuring process, because testing is to carry out in the high-altitude, and the operating personnel needs two hands hold checkout equipment simultaneously, has to make the operating personnel fall from high altitude easily with the fixing health of both feet, has very big potential safety hazard;
3. because insulator bunchiness shape, axial dimension is longer, in measuring process, need the hand-held checkout equipment of operating personnel constantly to move the detection of carrying out each section of insulator, and in every section detection, need to make the test side of two steel bar test pencils and the careful contraposition of insulator to fit again, complicated operations flow process like this, cause detection efficiency low, can't finish a large amount of testings on schedule;
4. intelligent detecting instrument is after energising, and the test pencil test side promptly has high pressure, if this moment, the operating personnel touched the test side because of carelessness, then causes most probably getting an electric shock, and causes personal injury.
In the above-mentioned situation, the lighter's insulator is measured inaccurate, inefficiency, and weight person operating personnel is injured, so be badly in need of the checkout equipment of prior art is improved.And the inventor adopts the new test pencil of design to connect the combination of existing detector according to its working experience in the industry for many years, overcomes the problems referred to above.
